The template strand of DNA is 5’-ATTCAG-3 ’ , its transcript is
举一反三
- The 5'→3' exonuclease activity of intact DNA polymerase I can replace a segment of DNA (or RNA) paired to the template strand, in a process known as ____________________.
- The sequence of part of a DNA strand is the following: -ATTCGATTGCCCACGT-. When this strand is used as a template for DNA synthesis, the product will be which one of the following?
- If the DNA strand shown below is used as a template for RNA polymerase, what would be the sequence of the resultant mRNA following transcription? 5'-CATTCCATAGCATGT-3'
- 现有一DNA片段，它的顺序为3′……ATTCAG……5′，转录生成的RNA序列应是 A: 5′……GACUUA……3′ B: 5′……AUUCAG……3′ C: 5′……UAAGUC……3′ D: 5′……CTGAAT……3′ E: 5′……ATTCAG……3′
- The DNA polymerases require a primer. A primer is a strand segment (complementary to the template) with a free 3′-hydroxyl group to which a nucleotide can be added; the free 3′ end of the primer is called the ______________.
